Whether moving into a new building or renovating an old building: Ugly walls are often a problem when buying a house. Many think of plastering the walls as the first solution. This is not only complex and takes a long time, but also takes a lot of drying time afterwards. In contrast, the use of plasterboard is much faster and relatively simple.

But even if gluing the panels is easier than applying a plaster, you should carefully inform yourself about the process before you start gluing. Because at the latest when the adhesive is mixed, the first questions arise. We explain step by step how nothing goes wrong when using plasterboard.

What are gypsum plasterboards?

Many hobby craftsmen don't dare to plaster walls and prefer to use plasterboard to renovate walls. This makes perfect sense because they are much easier and faster to use.

Plasterboard has a plaster core and an outer layer of cardboard. Gypsum plasterboards are available in different versions, which differ in weight and size. Plasterboard, however, should not be confused with gypsum fibreboard: with plasterboard, the cardboard box serves to ensure the stability of the entire board. In the case of gypsum fibreboards, cellulose fibers, as they are also contained in cardboard, are mixed directly in the gypsum and pressed into panels.

Can you adapt plasterboard?

Gypsum plasterboards are not only relatively easy to process, they can also be divided or adapted. This always comes into play when the panels do not quite fit the wall to be clad. To do this, simply scratch the plasterboard on the side on which the cardboard layer is located. The cardboard should be cut through completely. The rest of the material can then be easily broken over an edge and thus adjusted.

Is plasterboard the same as plasterboard?

Often the term plasterboard is simply replaced by the term Rigips or used interchangeably. But: Not every plasterboard is a plasterboard, because Rigips is just a brand name and describes a brand that produces plasterboard. So plasterboard is plasterboard, but not every plasterboard is a plasterboard!

Where are gypsum plasterboards used?

Gypsum plasterboards are mostly used in drywall construction. In principle, drywall construction is the opposite of a brick wall: it is a framework made of metal or aluminum, which is clad with plasterboard. In most cases, mineral or glass wool is used for insulation between the stud frame and the plasterboard.

Gypsum plasterboards are the perfect drywall alternative to plaster. The method works both in new buildings and in the renovation of old buildings.

Old building renovation: How to prepare the surface for plasterboard

An old building renovation is a lot of work. And also when installing plasterboard, there is significantly more effort than in a new building. Because the walls in old buildings are often crooked and not really well prepared for the plasterboard. Therefore the most important step is the preparation and preparation of the surface. If the old plaster is loose, incomplete or very sandy in some places on the wall, it must be removed and reapplied.

You should also apply a primer to ensure that the panels stay in place before you start to glue them together.

Before you start mixing the glue, you should cut the plates to the correct size and draw the correct distance from the wall with a pencil. This is the only way to glue the plasterboard as a flat and exactly vertical surface, even on crooked old building walls.

New building: plasterboard instead of plaster

The advantage of new buildings is that the walls are usually straight and well prepared for the plasterboard. This makes work a lot easier. Thanks to the straight walls, the plaster slabs for gluing the panels are also smaller. This saves space between the wall and the panel and creates a few centimeters of valuable living space.

Plasterboard: How to mix the plaster glue properly

When gluing plasterboard, gypsum serves as an adhesive. Before mixing the plaster, you should read the instructions on the package carefully and follow the manufacturer's instructions. The mixing ratio of water to gypsum powder is particularly important here. The glue must neither be too firm nor too liquid. Be sure to add a scale as an aid.

Fill a bucket with water. This should have the best room temperature. Then slowly and carefully sprinkle the gypsum powder into the water. You should not pour too quickly here, otherwise so-called plaster bulbs will form, i.e. unsightly bubbles in the plaster. Let the mixture settle for half a minute and then mix with a whisk for the drill. One to two revolutions per second are the perfect speed for this. The creamy plaster can now be used as an adhesive.

Our tip: It is best not to mix too much plaster at once, but to mix it several times during gluing. This ensures that the adhesive does not become too dry and therefore no longer adheres so well.

Gluing plasterboard: guaranteed to work

The distances are shown, the panels cut, the adhesive mixed: Now the plasterboard can be glued. To do this, apply the mixed plaster as an adhesive with a trowel at a distance of about 30 centimeters to the back of the plate. Apply the adhesive as chunks and do not spread them. Leave a margin of about five centimeters free so that the adhesive does not press out laterally when the panels are put on.

Now start gluing the plasterboard at the bottom of the wall and work your way step by step. Important: Do not place the panels flush with the floor, but use small wooden strips as spacers. This is how you guarantee impact sound insulation.

If the first row is glued, check the result with a spirit level. If the plates are not straight, correct them as long as the adhesive has not yet hardened.

The next row of gypsum plasterboards is now being moved, i.e. always placed in the center over two glued boards to avoid continuous joints.

If the entire wall is glued, the plaster must harden and dry. Depending on the weather conditions, this will take different lengths of time, which is why it is advisable to only start work after a few days.

When the gypsum has dried, the joints between the boards must be filled and then sanded. An acrylic joint can be placed between the plasterboard wall and the ceiling.

The plasterboard wall is finished. It can now be papered and or painted.

If you have glued plasterboard in the bathroom or kitchen, you can also tile it.

Lay tiles on plasterboard

If you have glued the plasterboard in the bathroom or kitchen, you can also attach tiles to the boards. The standard DIN 18352 provides information on how tile work should be completed. If you are unsure about the installation, you should bring in a tiler as an expert and carry out the work with him.
